It has not, at least not as of a few weeks ago. There is absolutely no OLCI at HA for non-domestic flights (I don't fly domestic on HA, so I can't comment on those flights and agree that the domestic subset of flights may have OLCI). HA agents have confirmed it and have no clue when and if ever HA will get around to implementing OLCI. I've asked every time I've had to stand the 20 or 30 minutes in the J line just to check in at the airport. Airport checkin remains disorganized, be it in T2 (Japan flights) or T1 (other flights). And it's silly to have to check in at T2 for Japan flights (where the lines are always very, very long) when you have no bags to check, then walk outside along the road back to T1 for security and gate access.

The massive HA downgrade recently to a cheaper reservation system also removed ability to even pull or print your ticket receipt, among other things. Flight search still takes five fold longer, as the search isn't saved if you go back to change the date, and for non-revenue flights there is no more tab selector for different dates. I could go on and on, but the rate at which functionality is being removed is alarming. Most other airlines add functionality, HA only removes it.
